Specification of Letters Patent. Patented Apr. 26, 1910.

Application filed November 23, 1908. SerialNo. 463,952.

lily invention relates to improvements in gas lamps, and the ob ect o'lmy invention lS to produce a high elliciency andv high power lain whichwill ivc a much "renter li 'ht D h C than any ordinary inc-amlesccnt gaslamp, and which has means for inducing an unusual supply of oxygen tothe. burners, and for carrying oll'any waste products of comloustion,thus causing au' unusually high heat and consequent great light at themantle, and further furnishing good ventilation in the room.

I am aware that attempts have been made to force the draft onincamlescent gas lamps, but usually the only means of promoting suchadditional supply of oxygen and for carrying away the products ofcombustion, has been by utilizing the rising heat and gas currents fromthe lamp to turn a wheel which would propel a second wheel below theburner to force the air to the lamp. These devices are absolutelyinadequate to produce the desired result, as, the wheels turn withfeeble force and one practically couutcrbalances the other. Forced drafthas also been provided for gas lamps by either com- .vressing the gas orcompressing the air and forcing these gases under pressure through theBunsen burner, but apparatus of this kind involves the use oft'XpellSlVc and complicatcd machinery, which is not only expensive toinstall, but to maintain; whereas with my invention but little power isneeded to exhaust the air from the globes, and the natural inrush oioxyg'en follows. Furthermore, where pressures are used which cause thegases to flow in with great velocity, special mantles are required whichmust be made much stronger than the ordinary commercial mantles towithstand the said increased pressure, whereas by my method ofexhausting the air from the globe, no blast;

of ases or air is directed against the man ties, and lllu ordinary onessnllice. In carrying out my invention, however, I use globes which areair tight except at. the bots-Qt r'Fi'D. where he air supply iscontrolled, and connect tubes or pipes with the tops of the globes, andexhaust the air irom these tubes or pipes and consequently from theglobes, so that the products of combustion are carried on, a partialvacuum is created in the tops of the iches, and the inrushing air passesthrongi the Bunsen tubes thus crent- 6Q ing intense heat and highincandescence at a the mantle.

Obviously the detail construction of the lamp is not very important sofar as this particular invention ls concerned, so long as means isprovided for exhausting the globe and permitting the necessary influx oioxygen below the mantles and through the Bunsen tubes.

A. lamp of this character is especially adapted tor use in stations,stores, heaters, halls, and places where a great quantity of light isdesired, and in such places the lamp atl'ords great economy in lighting.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar reference characters indicatecorresponding parts in all the Flg'lll'c i is a sectional elevationshowing an arrangement of two lamps embodying my invention, and Fig. 2is an enlarged View partly in section, showing the construction of thelamp more in detail.

The lamp 10 may be any usual incandescent gas lamp, and as illustratedit has a bunsen 11 which also can be of any ap proved type, and this issupplied by a gas pipe 12 which permits the gas and air to llow throughthe bunsen to the group of mantles 13 which as shown, are verticallyarranged and inclosed in a globe 14. The, number of mantles isimmaterial, however, and the arrangement of the gas ipe 12 can be variedindefinitely without a octing the principle of this invention. It isdesirable, however, to provide for an inlet of air to the mantles, andso the globe holder 14 has, perforations 15 near the bottom, whichregistcr with the perforations of a movable collar 1'6, this bci'nsupported above the gallcry 13 on which the globe 14 rests.

The arrangement so far disclosed is not peculiar to this invention, andon the other hand this invention, is not limited to the structure abovese 'ot'th.

Each globe 14/ has an airtight top 17, and this top connects with a pipe18 which in turn 'eonncets by mehns of a pipe 19 with an exhaust fan 20,the discharge pipe 21 of which can be led off through an adjacent windowor into a chimney, or in any place where it is convenient to dischargethe products of combustion from the lamp. The fan can be run in anyusual way, can be of any approved construction, and as-shown is operatedby the motor 22. i

In Fig. 1, I- have shown two lamps in connection with a single exhaustfan 20, and obviously any number of lamps from one up to any reasonablelimit, can be con-,

nected with one set of exhaust pipes.

In operation it will be seen that when the air is exhausted from thepipes 18-49, the air is also exhausted from the upper part of the globes14, and consequently. a great quantity of air rushes in.through theBunsen tube 11 and through theholes 15, if these are open. The result isthat with the necessary flow of gas, a big su ply of oxygen is provided,and a wonderfully luminous lamp is produced.

Itwill be readily seen that this lamp besid-es burning with greatetliciency and high power, has the desirable qualities of not- -onlycarrying away the materials which usuall vitiate the surroundim air butit serves actually as a ventilator tor the room because it has atendency toexhaust the air from the room, which is replaced by theinrushing air which comes through every available source of supply inconnection with the room in which the lamp islocated.

The arrangement which I have described 'and shown has the furtheradvantage of being specially adapted for use in warm weather, as l findthat by artificially exhausting the air from the globe and. carrying itaway through a pipe, the heat is thereby carried away and the lampsradiate .very little heat.

described my invention,

Having thus fully desire to secure by Let- I claim as new a-n tersPatent 1- 1. An incandescent 'as lamp, comprising a containing globe, aunsen tube project? ing intothe globe and havin means for re-CGIVlIlgdlZS air supply from t eair immediately surrounding the globe,an exhaust pipe leadin from the globe to carry out the prodnets 0combustion, and an exhaust fan to.

exhaust the pipeandglobe, said fan being located near, the outlet of theexhaust pipe.

2.,An incandescent gas lamp having a containing lobe for the'lamp, apipe leadlng from a ove thelamp. to carry off the products ofcombustion, a Bunsen tube for the lamp, means for supplying air to theBunsen be at atmospheric pressure from the air ..nmediately surroundingthe lamp,

and an exhaust fan located near the outlet off the products ofcombustion, and means connected with and auxlllary to said exhaust pipeto increase said draft.

.4. The combination with a series of incandescent gas lamps having aninclosing structure adapted to shut oh the air inlet except through theBunsen tubes, means for supplying air to the Bunsen tubes from the airimmediately surrounding the lamps, a pipe connected with the inclosingstructure of the lamps, and an exhaust fan located near the outlet ofthe pipe to exhaust the air therefrom.

5. An incandescent gas lamp having an inclosing globe, a Bunsen tubeprojecting through the globe, means for supplying the air at atmosphericpressure to the Bunsen tubeirom the air immediately surrounding theglobe, a pipe leading from the upper part of the lobe, and means locatednear the outlet ot-the pipe for increasing the natural -draft thereof.
